TOTALIZING MECHANISM FOR CASH-REGISTERS.

Specification of Letters Patent.

Patented Dec. 18, 1917.

Application filed April 23, 1917. Serial N 0. 163,851.

To all whom it may concern:

Be it known that I, ROBERT FIELD, a subject of King George V of Great Britain, residing at Huddersfield, in the county of York, England, have invented a new and useful Improvement in Totalizing Mechanism for Cash-Registers, of which the following is a specification.

This invention relates to totalizing mechanism for cash registers of the key operated type and more particularlyto the type of cash registers described and claimed in United States Letters Patent of myself, No. 1,149,903, August 10th, 1915.

The primary object of my invention is to provide improved means whereby, in conjunction with the mechanism employed for exhibiting the amount of each purchase, the amounts indicated, whatever number of keys be depressed at one time or simultaneously in each registering operation, shall be totalized after each transaction so that the total amount taken can at any time be ascertained at a glance.

According to my invention I employ in conjunction with vertically movable indioat-' ing slides or tablets which are lowered to indicate the amount of each transaction, asin the type of cash register referred to, two separate sets Or series of wheels or notched or studded disks mounted on separate shafts arranged in axial alinement, one shaft and set of wheels for the silver and one for the copper, the operation of the tablets by the depression of the keys causing levers actuated thereby to place devices in the path of pawl levers which said devices on the tablets being raised to normal position, engage and oscillate the pawl levers and thereby partially rotate the respective toothed wheels to the desired extent and give a. proportionate movementto the respective shaft whereby the amount of the last transaction is added to the previous total registeredor totalized, transfer mechanism operating between the copper and silver banks to transfer the re" quired units of pence or shillings to make a unit of the next higher denomination to the silver bank or to a pounds counter or device. Totalizing mechanism of the pawl and ratchet type and with means to transfer amounts from a lower to a higher denomination are commonly employed in cash registers, my improvements being especially intended for cash registers of the type described in the specification of the patent referred to and designed principally to admit of any number of keys in each bank being depressed simultaneously and secure the totalizing of each transaction accurately.

The object and nature of the invention thus set forth will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

Figure l is a cross section taken on line l2 of Fig. 2 of a'key operated cash register showing a unitof my improved adding mechanism applied thereto;

Fig. 2 is front elevation looking in the direction of arrow X of the totalizing mechanism detached;

Fig. 3 is a cross section, taken on line 34 of Fig. 2, showing the transfer mechanism for halfpence;

Fig. 4 is a cross section taken on line 5-6 of Fig. 2, showing the mechanism for transferring given amounts from the copper to the silver bank;

Fig. 5 is a cross section taken on line 7-8 of Fig. 2, showing the mechanism for transferring given amounts from the silver bank to the pounds counter device;

Fig. 6 is an end elevation, partly in section, of the lever and cam device for bringing the indicating mechanism to zero, and for releasing the keys or locking them in normal position, and i Fig. 7 is a detail hereinafter referred to.

Referring to the drawing and firstly to Fig. 1, A represents the side frames and part of the inclosing casing of a cash register of the key operated type and B one of the keys whose depression by the pressure of the finger on its outer end causes through a connection C, a tumbling lever D pivoted at E on internal cross framework, to be oscillated and through pin connections with upper and lower slides F. G to withdraw slide F from the path of a projection H on a respective long indicator tablet I of which there are a series carrying indications of increasing numerical value. The withdrawal of the slide F and the projection of the slide G at the Fig. 6) which has uprights K carrying one way pawls L for engagement by a yoke M actuated by the hand lever P and yoke lVl the parts described are arranged and operated substantially as shown and described in my prior United States Patent No. 1,149,903.

My invention consists in applying to cash registers of the type referred to improved means adapted to be actuated oneach opera-.

tion of a key or a series of keys simultaneously to totalize the amount of the transactions so that the total amount of cash taken can at any time be. ascertained at a glance.

According to the invention, I employ two separat shafts or spindles a. 6 supported in axial a .ement. across the machine and journaled in suitable beari in the framework, the shaft a being provided for the copper bank or set, and the shaft 6 for the silver bank or set. Fast on the shaft a are a series of toothed wheels or notched or studded disks 0, one for each key 13, of which latter there may be any desireo number according to the combinations used in obtaining any amount from one penny upward to one shilling, for instance, the keys employed in this case represent respectively 1d., Qd.,3,d.' and 6d. There is also fast on said shaft a total indicating disk (Z bearing on the periphery two or more sets of numerals from zero to 11. In this instance four sets of numeralsfrom ,zero to ll'are provided on the disk; Loose on the opposite end of the shaft at is a toothed wheel or notched or studded disk 6 for the key for registering halfpence.

Onthe shaft 6 are mounted similar toothed wheels or notched or studded disks ffor the keys inthe silver bank or set of which also there maybe any number according to the combinations of amounts desired as for instance, in this case there is a key for (one shilling) 1/; one for (two shillings) 2/- and one for (ten shillings) 10/ there being provision in the registering mechanisms in the specification of the patent before referred to for multiplying any of these amounts, say, three times, by three distinct operations or depressions of their respective keys. Each toothed wheeler disk in the silver bank, with the exception of the wheel f. for the10/- key, is fast on the shaft 6.

On the shaft 1) is a total-indicating disk 9" for amounts from Zero to nine, or zero to nineteen as may be preferred. In the arrangement shown, the disk 9 has four series ofnu'merals running from zero to nine, on its periphery.

A separate counter device h is provided for pounds, this being adapted to be actuated from the wheel or diskwemployed in connection with the (ten shillings) 10/ key and from the silver bank, as will be hereinafter described.

Engagingwith. a pin or stud i on each individual indieator tablet I is the forked end of. a lever pivoted on a pin .or transverse spindle 7c. The opposite end of said lever is enlargedand has pivoted thereon a trip or tumbling or like lever Z normally resting at its tail endon-a stud m project ingfrom the lever and which at each depression ofthe respectivekey to. bring about the descent of the indicator tablet to indicatingposition, is caused, by the oscillation of thelever j, to wipe idly over the near end of alever n PlVObflllfy mounted on-the respective shaft a or badjacent the toothed wheel. corresponding to the. respective op eratingkey B.

1 On the .outerarm of the said lever 41 is pivotally mounted a pawl or push finger 0 which is adapted. on. actuation of. the said lever n, to engage'with atoothof the respective toothed .wheel 0..or fand turn it in one direction adistance equivalent to one,-two or more teeth accerdingto the number of pence or shillings represented by the key and as. determined by the extent ofmovement of the indicator tablets 1. The operation of said toothed wheels 0, f is effected when the indicator tabletsare returned to theirnormal or zero positions and the mechanisms are so timed that the operationstake placesuecessively, commencing atthe highest figure in theibank or set. For the operation oflthe totalizing mechanism'the hand lever P is firstmoved over in the direction ofthe arrow-R in order to remove a locking slide S from locking position under the several keys, as described in the specification of my patentbefore mentioned, the yoke M engaging a bell. crank lever T and through thesamemoving said. slide. endwise as ordinarily. This clocking slide forms no part of my. present invention.

.lVhen the hand lever P is drawn fully over toward the operator, the keys are free to be depressed and as-they are forced downwardly either singly or any number thereof simultaneously the descent of the respective tablets 'I rock the respective levers the enlarged ends of which are thus elevated. As the. said enlarged ends of the levers move upwardly, they carry the trip or tui'nbling levers '1 with them, the outer ends of said levers wiping idly over the near ends of the levers n and on passing clear of the same assuming a position above andin the pa h thereof. After-the depression of the keys to give indication of the amount of the purchase the handlever P is returned to normal position and no action takes place in respectofthe totalizing mechanism, but when the said hand lever is again drawn forward preparatory to registering the next transaction the cam N elevates the yoke M and raises the lowered tablets vto their zero position in doing which the respective levers y are rocked correspondingly, the descent of the enlarged ends thereof causing the trip or tumbling levers Z to engage with the up per edges of the respective pawl carrying levers n and, by virtue of being held by the studs m on said levers, cause the levers n to be rocked about their pivot centers whereby the pawls carried thereby advance the respective toothed wheels a distance equivalent to the denomination of the key, that is to say, the single pencewheel is advanced a single tooth, the 2d. and 3d. wheel a distance equivalent to two teeth and three teeth respectively and the 6d. wheel a distance equivalent to six teeth, the combined movements of the wheels transmitting through the shaft a to the total-indicating disk (Z a movement equivalent to the total of the units of the several wheels thus advanced. V

In the silver bank the same operations take place but, in this case, the keys may be depressed one, two or three times to give the amount of the key value or two or three times such an amount as in the specification of my patent before referred to, the second or third depressions of the keys causing the tablets to descend farther by one or more steps. In order to transmit the added motions to the, toothed wheels of thesilver bank, I provide on the enlarged ends of the levers'j a series of say, three trip or tumbling levers Z (see Fig. 7) one, two or all of which are thus elevated above the ends of the pawl levers according as the key is depressed one, two or three times these trip or tumblinglevers, if there be more than one elevated, operating therefore on the respective pawl lever in successive order as the respective tablet israised to its normal position whereby one, two or three successive oscillations is or are given to said pawl levers and the respective toothed wheel rotated to an extent to move it a distance equivalent to 1/ 2/ or'10/ or to twice or three times such amounts. 7,

lVith respect to the registration of halfpence, the respective toothed wheel 6 is loose upon the shaft a and has on one face thereof a series of pins 79 spaced at distances apart equivalent to two teeth. As the wheel 6 is rotated the said pins in .turn successively engage with a finger q (Figs. 2 and 3) on a short spindle r and rock the same, a second finger on said spindle engaging with the pawl lever n of the pence wheel and elevating, said lever sufficiently to causeits respective pawl to move the pence wheel one tooth. In order to indicate half-pence, the pins 79 successively engage with a lever s and rock a shaft 25 on the outer end of which is a half-moon or like device a having on its face the representation of a half penny and a blank portion, said device occupying a position adjacent the total-indicating diskd. Each odd half-penny registered is thus indicated by the position of this device presenting the representation of the half-penny opposite the pence on the total-indicating disk (Z but on registration of each second half-penny the blank on the device on the transfer spindle or shaft t is brought opposite the figure in pence on the total indicating disk cl and simultaneously therewith the pence wheel is moved to the extent of one tooth. Loosely mounted on the shaft b is a sleeve 1) carrying at one end the toothed wheel f adapted to bepartially rotated on depression of a key representing l0/-'- in the same manner as has already been described with reference to the keys of lower value. The opposite end of the sleeve *0 carries a toothedwheel w and a digit disk as which latter lies adjacent to the numerator disk 9 of the silver bank as shown at Fig. 2. The periphery of the digit disks as is divided into spaces correspondingto those on the numerator disk .9 and every alternate one of these spaces is marked with a 1 and each neighboring space is blank. Loosely mounted on a fixed spindle y is an arm .2 (Figs. 2 and 5) having a pin 2 projecting into the path of and adapted to be engaged by a. series of abutuients 3 on the disk 5/. These abutments are four in num 'ber, corresponding to the four series of numerals (Zero to nine) on said disk, and are so arranged that each time a numeralnine Passesa given point the respective abutment engages the pin 2 and rocks the arm 2. The Said arm carries a pawl 4 adapted to engage theteeth of the wheel 20 and each actuation of the arm causes the said wheel to be rotated a distance equal to one tooth, thereby rotating the digit disk one space and bringing a markedspace opposite a certain point in the periphery of the numerator disk 9, or presenting a blankopposite thereto. The wheel to has a series of. projecting pegs 5 which are adapted to engage a finger 6 on a sleeve 7 loosely mounted on the spindle y, the other end of said sleeve carrying a counter arm 8 adapted to engage and actuate the *star wheel 9 of the pounds counter. The pins on the wheel w are provided opposite everysecond tooth, so that rotation of said wheel, either, di-- rectly from the 10/ key or from the disk 9 will cause the pounds counter to be actuated each time the wheel to movesltwo teeth. If the 10/- key is depressed once or three times, giving an odd amount of 10/-, this will be indicated by the presentation of a l in front of the amount displayed by the total-indicating disk 1 of the silver bank, orjif the amount of silver already indicated exceeds.10/ then such actuation .Ofthe 10/ key will cause a digit mark .1 to be removed from opposite the indication of the disk 9, the completed pound being transferred to the pounds counter. Similarlyif the rotation of the total-inclicating disk g is such as to carry it past the last figure of one of its four series, then the digit disk in its consequent movement will either cause a l to be exhibited opposite the indication of the total-indicating disk or if the amount of silver displayed were already above 10/ then the rotation of the digit disk will remove the 1 from opposite the total eindicating disk and cause the pounds counter to be operated to record an addition of one pound.

'Transfers from the copper bank to the silver bank are effected as follows: The coppertotal-ind-icating disk d hasa series of abutments 10, four in number correspondingto the four series of pence indications zeroito 11 on its periphery. Extending into the path of, and adapted to be engaged by these abutments 10 is a pin 11 on a weighted pivoted lever or arm 12. The upper end of this arm, on actuation thereof by one of the abutments, is adapted to bear against and rock on its pivot 13, an arm 1% having a cranked portion15 adapted to bear against the rear end of the pawl arm n of one of the toothed wheels 7 on the shaft .7) of the silver bank. The rocking of the arm 12 by one of the abutments, on the disk (Z passing the last numeral of any one of its four series, causes the arm 14 to swing on its pivot until the upper end of the said arm 12 slips into a V-shaped notch 16 on the arm 14, thereby holding said arm in such a position that it can be engaged by the free end of a curved rocking lever 17, when said lever has a pivotal movement imparted to it. This pivotal movement of the lever 17 is brought about by means of the shaft 0 which is rockedat each movement of the hand lever P to its normal position. A finger 19 on the shaft 0 is adapted, in one direction of movement, to move idly under a swinging latch 20 on the lever 17, and in the other direction of movement to engage the latch and swing the said lever on its pivot so that if the arm 14 has been positioned :by the arm 12, the said arm 14: will be engaged by the lever 17 and the pawl arm n actuated to move the respective toothed wheel f one tooth, thereby partially rotating the shaft 6 and advancing the silver total-indicating disk 9 one unit.

.Any suitable known devices such as V toothed wheels or disks, may be employed to prevent overthrowing of the toothed wheels 0, 7 or f and to cause the indications ofthe respective total-indicating disks to be presented in exact alinement.

Slotsare formed in the inclosing casing on a line parallel with the shafts a, 6 through which the totals are exhibited.

If the parts have to be brought to zero at the end of each days takings, the counter would be replaced by a total-indicating disk or disks so that said disks could be turned forward by hand along with the numerator disks (Z, 9 and at to place the whole of them at zero.

The parts are so arranged or timed that the totalizing operations take place successively commencing at the highest figure in each respective bank.

Suitable springs retract the pawl carrying levers it after each actuation thereof, stop pins 21 limiting the return movement of said levers.

In employing my improved totalizing mechanism in the type of key operated cash registers hereinbefore referred 'to, any amount of purchase registered can be totalized after each transaction, whatever number of keys are actuated in making the registration and whether they are all depressed simultaneously or otherwise, this being of considerable advantage as ordinarily in totalizing mechanisms the depression of more than one key or given combination of say two keys at a time, causes the parts to jam and render the machine for the'time being inoperative.

It will be understood that the means for actuating the toothed wheels or notched or studded disks and for transferring motion from the pence to the silver bank or from the l1alf-pence to the pence numerator or from the 10/ to the pounds counter or shillings numerator, may be varied or modified without departing from my invention.
